Synopsis ========
The NBD server is vulnerable to a buffer overflow that may result in the execution of arbitrary code.
Background ==========
The NBD Tools are the Network Block Device utilities allowing one to use remote block devices over a TCP/IP network. It includes a userland NBD server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-block/nbd < 2.8.2-r1 >= 2.8.2-r1
Description ===========
Kurt Fitzner discovered that the NBD server allocates a request buffer that fails to take into account the size of the reply header.
Impact ======
A remote attacker could send a malicious request that can result in the execution of arbitrary code with the rights of the NBD server.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All NBD Tools users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-block/nbd-2.8.2-r1"
